Vedclass · Answer

(B) When a $PN$ junction is reverse biased,the negative terminal of the external battery is connected to the $P$-region and the positive terminal is connected to the $N$-region.This causes the free holes in the $P$-region to be attracted towards the negative terminal,away from the junction.Similarly,the free electrons in the $N$-region are attracted towards the positive terminal,also away from the junction.As a result,the width of the depletion region increases,and the height of the potential barrier increases,making it harder for majority charge carriers to cross the junction.
